The agreement is due to take effect in early April, AT&T said. Terms of the deal were not disclosed.

AT&T said on Monday it expects revenues from Yellowpages.com and content advertising, including ads on its mobile phones as well as its U-Verse high-speed Internet and video services, to exceed $1.5 billion by 2010, up from around $600 million in 2007.
